When her daughter Ashby was born in 2007, Nancy O'Dell was overjoyed; but she found the experience of pregnancy to be anxiety-provoking. O'Dell is host of the popular entertainment news show Entertainment Tonight.

After her baby was born she compiled her memories and thoughts into a book for first-time pregnant mothers. The book, “Full of Life: Mom to Mom Tips I Wish Someone Had Told Me When I Was Pregnant,” covers a wide range of topics — including oral health during pregnancy.

“While my dental health has always been relatively normal, pregnancy did cause me some concern about my teeth and gums. With my dentist's advice and treatment, the few problems I had were minimized,” O'Dell told Dear Doctor magazine. An example of her experience is a craving for milk that started at about the time the baby's teeth began to form. She felt that her body was telling her to consume more calcium.

As often happens with pregnant mothers, she developed sensitive gums and was diagnosed with “pregnancy gingivitis,” the result of hormonal changes that increase blood flow to the gums.

“I love to smile,” said O'Dell, “and smiles are so important to set people at ease, like when you walk into a room of people you don't know. When you genuinely smile you're able to dissolve that natural wall that exists between strangers.”
